SUBMERSIZBLE TOY SUBMARINE.

Specification of Letters IPatent.

Patented Aug. 12, 1919.

To all whom it may concern:

Be it known that I, SIGURD WIEBE, a subjeot of the King of Sweden, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Submersible Toy Submarines, of which the following is a specification.

This invention relates to toys built in imitation of submersible boats and has for its object to provide a toy of this kind which may be easily and cheaply manufactured, which will be simple and durable in operation and which is not likely to get out of order.

While herein, I have described minute details of one of many possible embodiments of the invention, the invention is not limited to these details, since the details of construction and combination may be greatly varied. or the construction may be adapted to uses other than submersible toys, without departing from the spirit and scope of the invention as claimed.

Figure 1 is a side elevation of the submersible toy boat.

Fig, 2 is a vertical approximately longitudinal sectional view through the boat.

The boat comprises a buoyant hollow hull 5 open at the front end. closed at the rear opening 6 in its lower part and a rear opening 8 in its upper part, both communicating with the interior passage 9 of the hull. In said lower opening 6, there is detachably secured a ballast plate 10 provided with a keel 11 and a forward opening 12 communicating with the passage 9.

The rear end of the hull is provided with an axial bore 14 through which is passed the propeller shaft 15,.pr0vided at its forward end with a hook 16, at its rear end with an exterior propeller 18, and at its intermediate part with an impeller 19 disposed forward of the rear opening 8. In the open forward end of the hull, there is rotatably mounted a winding head 20, from the rear face of which projects a screw-eye 21 between which and said hook 16 there are stretched strong rubber bands 22.

If desired, the forward part of the propeller shaft may be held in alinement by means at a erosepiece 25" secured: in open? ings in the side of the hull and provided w1th a bearing opening 26 receiving the propeller shaft at a point between the impeller and the hook 16. Upon the upper part of the hull, is placed the cabin 27 provided with a periscope 28 in order to more closely smrulate the appearance of a submarine boat. In the upper part of the rear end of the hull is a vertical bore in which is friotionally received a rudder post 29 carrying a rudder 30.

For holding the propeller shaft stationary while the bands are being wound up, there is provided a detent 31 pivotally mounted in a slot 32 just above the impeller 19. When this detent is in the position of the full lines, the impeller 19 is engaged and the latter and the propeller shaft 15 held against rotation. When the detent is shifted to the dotted line position, the impeller and shaft are free to rotate. The detent may be operated by hand or by a stick or even by a. proper projectile from a toy gun.

The bands 22 may be wound up or twisted by holding the propeller from rotation by means of the detent 31 or by hand, and retating the winding head 20 until the band is suffioiently wound up; or on the other hand, the winding head may be held stationary and the propeller rotated rearwardly until the rubber bands are sufficiently twisted. After this has been done, the boat is placed in the water and the band allowed to unwind, the detent being placed in the position of the dotted lines, thereby rotatmg the propeller and the impeller, propelling the boat forward and at the same time causing a current of water to pass into the boat through the lower opening 12, thereby causing the boat to be submerged and the boat to be propelled under the water. When this is done, the water flowing out from the upper opening 8 causes equilibrium between the openmgs 12 and 8, and causes the boat to travel horizontally forward. q

A boat having the required displacement relative to the weight of the'material, pref erably as illustrated, will normally float ,at the surface of the water. l/Yith the aforesaid relative displacement and weight, when the detent 31 is rocked to release the impeller 19, the rotation tbereot an sack water through the opening 12 into the passage 9 and out through the opening 8. The opening 8 is relatively smaller than the opening 12, and the reaction caused by water being impelled upwardly and through the opening 8, in the top of the boat, that .is, the downward pressure of the water as it escapes through said opening, will draw the boat down below the surface of the water, and according to the velocityofthe impe-llerlS will draw the boat down to a greater or less depth, whilethepropeller 18 will propel the boatforward. As the power isspent, and the velocity of the impeller decreases the boat will gradually rise becauseof the buoyancy of the boat until it again reaches the surface of the water when the impeller 19 has come to rest.

The head 20. or the ballast: plate 10 or both may be removed for applying new: rubber bands when desired. The rudder 30 is adjustable in any direction, whereby the boat. may be caused to travel in an-arc of a circle.
